usb: host: ehci-sys: delete useless bus_to_hcd conversion

commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 upstream.

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.

[bwh: Backported to 3.2: Unfortunately some EHCI platform sub-drivers
 point drvdata to a private structure, so only create and remove the
 attributes if drvdata has been set as expected.]
